Good for Vertical Bars
I've been using this silo waterer for many years on cages with vertical bars, for which it works very well. The birds also like to play with the part of it that sits outside the cage. But I have never had horizontal bars with which this silo would work. My experience says they're useless with horizontal bars, despite what the package says.
